Good afternoon gentlemen, Vito Cdi

Someone could tell me that I have to disarm to see the injectors of the Vito L CDI, it is 110, I am going to buy one and I would like to see that I do not have fogged injectors

The Vito injectors in that model are a lottery, I would not worry about that, since if they are well it may be that in 3 months they fail.
It is a very sold and sure model that in scarf, secondary or spare parts should not be very expensive compared to other pieces of that van.

Look at the kilometers/miles that that engine has and look for wear of use in pedal bodies switches that can indicate that those kilometers/miles are real.
You can go to a Mercedes dealership that puts the machine and internal memory does not lie.
Look for corrosion in the chassis below and that the engine does not pray oil or lose liquids.

In Spain you try to buy a second -hand car and everyone has 75.Mil kilometers per old man.

You remove the plastic housing and you see them. You take away the clicks that hold the excess tubes the current chips and some screws that take them to the cylinder head as a madman that will be stuck.
